lleferring to the dra wings a vertical Shaft 1 is mounted in a linee Q and carries a gear fl which meshes with a lt-ar 4 on a driving shaft 5. Power is applied to the driving shaft in any suitable manner. A head 6 is carried by a frame 6 mounted on the upper end of the vertical shaft and secured to re tate with the shaft 'oy one or more feathers T. The head is in the form ol a tank which is cloaed in an air tight manner hy a, cove S. The tank carries a nummer of bottle lling mechanisms dependingr from its hottom. but in Fig. 1 I have shown only two of these mechanisms to avoid confusion. llac filling mechanism which formsy the subject matter of my application No. 255153 filed April 13. 1905. comprises a plate 9 fastened o the bottom of the tank over an opening lll the filling mechanism. A valve hloek 11 is slidably arranged on the suapension rods 19. which depend from the plate 9 and are provided on their lower ends with nuts 13 to hold said block on the rods, The plate 9 and the bleek 11 are centrall apertured to slide ably fit on the vertically movable filling tnhc 14, stalling boxes l5 being provided to pre vent leakage. A coil spring 16 i5 mounted on the tilling tube betwr n.the upper ,falling box and a fixed collar 17 and coil springs 1S so i ` vided with an axial duct 3l trq'iping the are mounted on the suspension tufts 11.'. the upper end of the 'filling tuhtl is ,a tatie disk 19, the lower operative tace ot tvhit'n is flu' provided with a fibrous ,or other parking` ring 20 and immediately beneath this,y ring 22. A rod 26 having thereon a pair ot scpN arated pistons 27. 2T is arranged to operate in a cylindrical chamber 28 in the valve block and this chamber communit'iitcs` with the branches 22.22 by means of ductsihy'tl'. This rod extends above the valve hlt-,ck and carries a coil .spring Il() brtweeu tht upper Said Spring normally holding the pistttiu in the elevated position shown in hic'. nozzle 3l on the valve blot/k is connected hv a flexible hose 32 (Fig. l) with the interior of the tank at or near its 'top and is procylindrical chamber about midway ol its length. A nozzle 33' has attached thereto a drip hose 34 (Fig. ll that may discharge into a trough on the vertical shaft an-l tions of pressure slow and regular operations. 0n the downward movement of the hottie the springs 1G and 18 force downward thc filling tube and valve block l1 and the pistons 27, 27 will rise in the chamber 28 until, just before the bottle breaks its seal against the seat 36, the lower piston 2T uncovers the mouth of the duct 119 and permits such air or gas pressure as remains iin nicdiately under the seal or in the neck ot i the bottle to blow out quickly threugh the brauch 22. duct 29'. t't'liuder 2S and eX- l aust duct 33 into the drip lu te 3"4 to the operated valve 25 is located in the branch trough 35. thus rlicrting thtI hitting of the hott-lc. When the liquor is of' value it can he returned from the trough to its source of supply.

The tank herein shown is of annular form having :i central opening 3T and the liquid tripes are siu'qiortcd within sait opening k tui thtA Vtraine 6 and discharge into the botpiston head and a nut 30 on the upprr end of said rod which abuts against lluA pate St,

this nozzle has an axial exhaust duwt Bbl l which taps the cylindrical chamber at it.-y l

i tity oi liquid in the tank. 4VVl'ien this air escape valve is closed a pressure equal to the hydrostatic head of the inflowing liquid will bottle and the tank through the air pasteleront nl the tank. AV centrally disposed feed pipe fl discharges into the pipes 38 and a -l uiting box 39 is provided to prevent leakage. A pressure indicator 40 and a gage Vll are arranged on the tank at convenient points for observation. A float 42 located within the tank and carries a valve 43 which is normallyseated to close an air escape passage 44. This air escapey or blow-oft' valve may be of any suitable construction ind it is adapted to allow the escape of air troni the tank and permit the inflow of liquid as occasion requires to maintain, suhstantially, a constant predetermined quanhe created in the tank to arrest the fiow of t thc liquid until the level of liquid in the the valve block wil] be moved upward to first open air communication hmm-glu thet in the valve block and the dort Ill and hi u 3 32, and thus permit an etpialf/.ation ot' pr sure therein. after which the liquid ruhe opened to permit the liquid to [low into t'lu i fillingl operation and also provides4 for thtI snifting ofi' of the compressed air and liquid immediately under the seal when filling completed and before the seal is e,liet-t:,|ally broken. It is found in practice that the sudden release of the seal7 which neces- Sary t0 close the fluid valve. disturbs fluids containing gas, and this invention provides` for the same gradual return ot the bottle to atmospheric pressure that takes place in the first operation when the bottle. which is normally under atmospheric pressure is, gradually raised to the pressure in the tank before the fluid starts to flow. It is a question of tank has been lowered by filling operations, when the valve will be automatically opened to relieve the tank of excess air pressure so that theflow of liquid will resume until a condition .ot equilibrium is again reached.

A spider 45 (Fig. 1) is slidably mounted ru the vertical shaft but made fast to turn therewith andV this spider carries a number of air-litt cylinders 46 located in vertical maintained in the tank and bottle during tht balancing pressures and making all altr-ia alinemcnt with the filling tubes and ach provided with an a ir escape port 46. In f. ach of the cylinders 4G is a piston rod 47 (Fig. t3) carrying on its lower end a piston 48 and on its upper end a shoe 4.9 adapted to support. a bottle. This shoe is preferably made in rectangular form. and the bottle is positioned thereon against upstanding walls 49 located at the inner edge of theshoe aud at its side edge which is rearmost in the direction of travel of the she.

The main air valve comprises a pair( of valve members surrounding the vertical shaft between the base and the spider. The lower stationary member 50 is secured to the top ot' the base and the upper rotary member 51 is slidable on but made fast to rotate with the vertical shaft. This air valve is shown in Figs. 5, 1() and 11 and by reference thereto it will be seen that the upper niember is provided with a number of angular ducts 52 which communicate through horizontal pipes 52 and vertical pipesl 53 with the bottoni of the lift cylinders 46. Thy. lower member of the valve (Fig. 11) has an inlet air passage 54 and an exhaust air lpassage 55, both being arc-shaped and the former having about twice the length of the latter. To the passage 54 air is admitted through a port 54 from a suitable source of supply and from the exhaust passage 55 air is discharged through a port 55. Between the two valve members 50 and 51 is a fibrous washer 56 superposed on a soft rub ber washer 56` and thesewashers are restrained by any suitable means against rotafion and have arc-shaped ports (fo-extensive and registering with the underlying ports .1?. :"7' which communicate with the passages iii., .3.5 respectively` in the lower member. (Fig. 5). The upper member 51 of the main air valve seats at its lower end on the washer 56 and the angular ducts in this member are adapted to register with the ports on the washers which in turn register with .the ports in the lower member. The upper member is held against its seat by a number of springs 58 located between said member and a collar 59 adjustably carried oy the spider 45. The tension of the springs 59 can be increased or decreased by adjusting the nut 59 to compensate for variations in the initial air pressure in the main air aire Hy this means the heavy load of the member and spider is balanced on its in avoid undue rubbing and wear. i au pigra' c.mmunioates by a conrpz El? with the bottom of the air oi U. a larger port 61 with 11 ate-:11e its bottom pipe :33 1 provide a in the form of a f c hown in Figv 7. o afford a e caring square suriarf hr is ,secured tionary wall hinge. l upm the flat surface and against the propassage from the cylinder through the esv cape port 6G. This is desirable when a bottle having a defective mouth is placed in .the machine. which would allow the liquid to spurt out. In such case it has been the practice to shatter the bottle to allow the filling valve to close` but by turning the cock (l5 the air is exhausted from the lift cylinder and the bottle descends to permit, the filling valve to close. thereby avoiding the danger and litter occasioned by breaking the bottle. 4

The bottle is centered to receive the filling tube by a' bell G8 (Fig. l) carried by a bracket 65) mounted to slide. freely on the vertical square rod 70. This rod is mounted with capacity for turning on its own axis in a bracket 71 at its upper end and in a segnient plate 72 at its lower end, the bracket being made fast to the frame 6 and the segment plate being fastened on the spider 45. 'l'his segment plate (Fig. 9) has an arcshaped slot 73 to receive the bolt74 oy which the plate is fastened to the spider. By loosening the bolt and moving the plate to one side or the other` usin the rod as a center, the rod will be axially adjusted to swing the bell to a position in which it will be axially concentric with the axis of the filling tube.

The parts of thc machine are constructed `and the operations timed so that immediately after the bottle is placed on the shoe it will be moved up into filling position and remain in this position until the shoe approaches discharge position comparatively close to the position where it received the bottle. A discharge mechanism is located to receive the filled bottle immediately after it has returned to its lowered position, and this meclmnism comprises a standard 75 which carries a guide chute 76 on its upper end. One side wall of said chute is constituted by an adjustable member 77 (Fig. 12) and the other side wall is constituted in part by a smtionary portion 78 and in part by a Wing T) hinged at to the stationary part 78. The, hub of the v f, 79 has on its rear side a projection el and an adjacent flat or .k strong leaf spring 88 tbrfczgh a block 8l. to the sta- .7n some distance back of the The free end of the spring bears iection on the hinged wing and with suffirient pressure to hold the wing in its nor- :ual position. illustrated in full lines in Fig. 3;: in wluch it lies across the ath of the bottles and above the plane of t e shoes. This jing; wiperates with the side edge wall 49 -t' each succeeding shoe to deflect the bottles u 'ward into the chute as they approach the om but if for some reason the bottle is not n dried down .to its lowered position the Ene or thepiston carrying the shoe will Aequilibrium of pressure in the tanks and strike the wing and swing it backward as shown in dotted lines whereby the operation of the machine is not interrupted and the parts are not injured.

l have shown and described the bottle lifting mechanism as operated by air pressure7 butl obviously any suitable form of fluid pressure may be employed for the same purpose.

When the machine is used in the filling of heavy liquids. such as c tsup or other liquids not charged with air or gas and hence not liable to foam duringr the filling operation, the moans described for maintaining an bottles may be dispensed with or rendered inactive by allowing the interior of the tank to remain in constant communication with the atmosphere. But in the lilling of all liquids under counter pressure when the pressure in the bottle to be filled is atmospheric only up to the time it is carried into filling position, it is necessary that this atmospheric pressure should be reinforced from the eonstant pressure maintained above the liquid in the head Vof' the machine, and this reinforcement should take place and be absolutely balanced with the pressure in the head betore the liquid valve is opened. It is therefore apparent that an arrangement which permits of a pause in the movement ot' the bottle to enable perfect sealing of the bottle before opening the air duct from the head of the machine to the bottle, and another pause immediately prior to the opening of the liquid valve to give time for the establishment of an equilibrium of pressure in the head and bottle, is of high value particularly when obtained by the simple means of the natur.l described.

The operation of the machine may be briefly described as follows The liquid to be filled is allowed to flow into the tank and the air therein will escape through the valve 43 until this valve is closed by the rising of the lloat. 42, after which the air in the tank is compressed until the hydrostatic head or pressure of the liquid at its source of `supply is equaled whereupon the flow of the liquid ceases. 'lhe machine is placed in operation to revolve the vertical shaft and the parts carried thereby and bottles are placed upon the shoes while the latter are in lowered position. VVhon each of the duets 52 registers with the port 57 that communicates with the inlet passage 54 of the main air valve, compressed air from the reservoir (not shown) fiows through the ronduit formed by the pipes 52 and 53 and l through the duct 60 to the bottom of the piston causing the latter' to rise slowly and carry the bottle against its seat 36.

passingl the duct 61 the piston will rise more ra ,idlyl but still gradually. The bell 68 cenil ters the bottle in its upward movement to After i receive the filling tube and the bell is carried upward with the bottle. The bottle engages and raises the valve block 11 and in so doing establishes communication first between the bottle and the air space in the top of the tank and then raises the liquid valve to permit liquid to flow into the bottle slowly by gravity until the bottle is filled. lhe bottle may be filled before the machine has completed its cycle of operation and this is an advantage because it. gives time for the liquid to become quiescent/which tends to avoid foaming. During the filling operation the air in the bottle displaced by the liquid will flow into the tank and when the fioat opens the air valve 43 this excess air will escape to reduce the. pressure in the tank below the hydrostatic pressure of the liquid and permit the replenishing` of the supply of liquid in the tank until the air escape valve has been closed by the rise of the float and the hydrostatic pressure ot the supply liquid has been exceeded by the pressure in the tank. The valve 25 in the air passage 22 enables the machine to be set to obtain perfect smoothness of flow with liquids varying in density or chemical com osition.

T e valve 62 in the air connection between the main valve-'and the lift cylinder controls and governs the flow of air into the cylinder and provides for a high velocity. Considerable expansion takes place below this valve which insures a reduced pressure operating under the piston until a resistance is met when the bottle engages valve block 11; then in a period of time. during which air communication bet-Ween thchead and bottle is established, suicient pressure will accumulate to overcome this resistance and thereafter expansion and consequent reduction of pressure occurs until a second resistance is met when the valve block is carried into engagement with the stop 17 preliminary to opening the liquid valve. In a period of time sufficient pressure will again accumulate to overcome this resistance and permit the valve block to rise farther to open the liquid valve. This valve enables the use of a. high reservoir compression to overcome resistance and at the same time produces a comparatively slow and gradual intermittent movement of the piston when the resistance is small and a rest. period of high mechanical value when resistance met to erxnit accumulation of pressure. When the air duct 59 arrives in communication with the exhaust passage 55 of the main air valve the air in the cylinder will escape to the atn'iosphcre and this per mitsI the piston to fall rapidly because the valve 62 will be lifted `from its seat. After thc piston passes the duct 61 in its downward movement (Fig. 6) it will be arrested t hv roast... of the fact that the duct 60 is vention to such details and arrangement ot' Anation of a rotatable tank, a. plurality ot' restricted in area and hence a cushion will be formed by the air between the piston and the bottom of the cylinder after the piston passes the duct 6l. This cushion is ot' iniportance in preventing shocks or jars to the mechanism which would llave a tendency to agitate the liquid in the bottle.

I have shown a puppety valve 62 but any form of check valve suitable for this purpose may be employed and it will be understood that this valve is of considerable iirr portance for the reason that it provides for a `gradual rise and a rapid fall of the lift piston. The lowering of the filled bottle to discharge position may therefore he delayed um the discharge mechanism has been closel)Y approached and the filling operation may thus be permitted to take place through a large are of the circle through which the bottle travels so that the fillin operation may be conducted slowly and t le liquid in the bottle may be given a substantial period of rest. before the bottle is discharged. This rapid lowering movement of the bottle after being filled also enables the liquid valve to close quickly and thereby avoid the loss of liquid.

It may happen occasionally that the operator will fail to place a. bottle on a shoe and to prevent `any shock or jar to the machine in such event I rowde a cushion above the piston 48 which .may be in the form of a spring 85 on the. piston rod adapt ed to be compressed between the piston and the head of the cylinder, or in the form of a. dash pot 86 as shown in Fig. 13. This cushion will prevent the piston from striking the cylinder head on its upward move ment when no bottle is on the shoe and thereby relieve the machine from shocks and jars h v reason of such conditions.

It is evident that the machine as herein shown and described might be considerably modified and varied in respect to the details of construction and the relative arrangement of parts without departing from the principle or sacrificing any of the benelits of the invention and hence I do not limit the inparts except to the extenthereinafter indicated by specific claims.
